Hi Liz, I'm so sorry that You're going through this with Bo, and that he's not feeling well. It definetely sounds like he's having an allergic reaction to something, especially since the Benadryl is working. Maybe he's reacting to the chicken in his new food change, since this is a recent change. I'm having the same issues with Blossom and Dozer with chicken and beef, and recently switched them to Fromm's Lamb and Lentil, they are better, but still seeing them lick their paws, and Dozer has some clear eye boogers. I'm running out of proteins since Blossom is allergic to chicken, salmon, beef, corn and grains.
